Hi everyone!
I am struggling since quiet some time with a problem in joule heating in thin films. I have a resistor on a microscope glass slide and I am able to simulate Joule heating on the glass slide. I used the Electric current, Shell and the Heat transfer in solids module. The resistor lines are 50 micrometers wide and 100nm thick (Shell thickness parameter). I used the "Heating Circuit" model (www.comsol.com/model/heating-circuit-465) as an example, ignoring the thermal stress aspects since I am not interested in them.
I want now to simulate the heating of another glass slide placed on top of the heating element (hence partially covering it). The problem now is that the boundary condition "Boundary heat source" that I applied to the circuit is shown as "not applicable" most likely because the second glass slide is covering it. (see the attached file).
Does someone have an idea how to fix this? Maybe the approach I am using is not the right one, if that's the case please let me know.
Many thanks.
Julien
